# Environment Reference

Task allows you to configure some behavior using environment variables. This
page lists all the environment variables that Task supports.

| ENV               | Default         | Description                                                                                                                                        |
|-------------------|-----------------|----------------------------------------------------------------------------------------------------------------------------------------------------|
| `TASK_TEMP_DIR`   | `.task`         | Location of the temp dir. Can relative to the project like `tmp/task` or absolute like `/tmp/.task` or `~/.task`.                                  |
| `TASK_REMOTE_DIR` | `TASK_TEMP_DIR` | Location of the remote temp dir (used for caching). Can relative to the project like `tmp/task` or absolute like `/tmp/.task` or `~/.task`.        |
| `TASK_OFFLINE`    | `false`         | Set the `--offline` flag through the environment variable. Only for remote experiment. CLI flag `--offline` takes precedence over the env variable |
| `FORCE_COLOR`     |                 | Force color output usage.                                                                                                                          |

| `TASK_COLOR_GREEN`          | `32`    | Color used for green.   |
| `TASK_COLOR_YELLOW`         | `33`    | Color used for yellow.  |

| `TASK_COLOR_BRIGHT_RED`     | `91`    | Color used for red.     |
| `TASK_COLOR_BRIGHT_GREEN`   | `92`    | Color used for green.   |
| `TASK_COLOR_BRIGHT_YELLOW`  | `93`    | Color used for yellow.  |
| `TASK_COLOR_BRIGHT_BLUE`    | `94`    | Color used for blue.    |
| `TASK_COLOR_BRIGHT_MAGENTA` | `95`    | Color used for magenta. |

All color variables are [ANSI color codes][ansi]. You can specify multiple codes
separated by a semicolon. For example: `31;1` will make the text bold and red.
Task also supports 8-bit color (256 colors). You can specify these colors by
using the sequence `38;2;R:G:B` for foreground colors and `48;2;R:G:B` for
background colors where `R`, `G` and `B` should be replaced with values between
0 and 255.

For convenience, we allow foreground colors to be specified using shorthand,
comma-separated syntax: `R,G,B`. For example, `255,0,0` is equivalent to
`38;2;255:0:0`.
